The French government has put the entire country on high alert for bird flu as the virus spreads across Europe, the agriculture ministry said on Friday.

The move will extend a requirement to keep poultry flocks indoors, a measure already implemented in certain areas since September, Reuters reported.

"Since the beginning of August, 130 bird flu cases or clusters have been detected in wild animals or on farms in Europe," the ministry said in a statement, adding that three cases had been identified among backyard birds in northeast France.

"Reinforced prevention measures will therefore be implemented to protect poultry farms."

The requirement to keep flocks indoors will be adapted, however, to take into account production practices such as free-range farming, the ministry said.

Elsewhere in Europe, Dutch authorities last week ordered commercial farms to keep all flocks inside after bird flu was reported on a farm.

France's measures will not threaten the bird flu-free status the country secured in early September after a previous wave of bird flu, the ministry added.

France culled about 3 million birds last winter in its southwestern duck-breeding region as it grappled with the spread of the virus from wild birds to poultry flocks.

Squirrels might look like adorable, nut-hoarding furballs, but some are ruthless predators that hunt, tear apart, and devour voles.
That's the startling finding of a new study published Wednesday in the Journal of Ethology -- the first to document widespread carnivorous behavior in these seemingly innocent creatures.
"There is always something new to learn and wild animals continue to surprise us," lead author Jennifer E. Smith, an associate professor of biology at the University of Wisconsin-Eau Claire told AFP.
"In a changing world with many technological advances, there is no replacement for direct observation of natural history, including watching the squirrels and birds that often visit our backyards."
The observations were made this summer, during the 12th year of a long-term study conducted at Briones Regional Park in Contra Costa County, California.
Between June and July, researchers recorded 74 interactions involving California ground squirrels and voles, with 42 percent of them involving active hunting of their fellow rodents.
Co-author Sonja Wild, a postdoctoral researcher at the University of California, Davis, admitted she was initially skeptical of the reports brought to her by undergraduate students who first witnessed the behavior.
"I could barely believe my eyes," said Wild. But "once we started looking, we saw it everywhere."
It was previously known that as many as 30 species of squirrels opportunistically consume meat, ranging from small fish to birds. However, it was unclear whether this behavior stemmed from scavenging or active predation.
The new study is the first to confirm that hunting is, in fact, a common behavior.
Researchers observed squirrels crouching low to the ground before ambushing their prey, though more often, they chased voles, pounced, and delivered a neck bite followed by vigorous shaking.
The study also found that the squirrels' carnivorous behavior peaked during the first two weeks of July, coinciding with a surge in vole populations reported by citizen scientists on the iNaturalist app.
Other animals, such as raccoons, coyotes, and spotted hyenas, have been known to adapt their hunting strategies in response to human-induced changes in their environments.
"In a changing world, it can be daunting to consider all of the challenges that human presence, habitat loss, and climate change impose on animals," said Smith.
"Our study offers an exciting silver lining, demonstrating the incredible flexibility that some animals possess."
Several questions still remain unanswered.
Researchers hope to investigate how widespread hunting behavior is among squirrel species, whether it is passed down from parents to pups, and how it affects their broader ecosystems.
